To ./zZZ whom 'L'tmay concern: y l

Ile it lmownthat I, .FRANCIS J. STUART, a citizen ofthe United States, residing at St. Louis, in the State of Missouri, have inf vented new and useful Improvements in Truss-Pads, ofv which the following is a specification.

My invention relates to a pad for use connection with trusses designed for the stantly. applied treatment of hernia, and particularly to a truss pad adapted to be held in position by means of a suitable support and which is hollow to contain a medicament, the pad being formed with an opening in its bearing face through which the medicament is conto the part under treatment.

One object of the invention is to provide a pad of the character ldescribed which may Abe manufactured from paper fiber, or` hard rubber substitutes, in a satisfactory and economical manner.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being hadA to the accompanying drawing in which Figures 1, 2 and 3 are respectively front,

rear and edge views of one form of'pad constructed'in accordance with my invention.' Fig. 4 is a longitudinal section of the same. Fig. 5 is a view similar to Fig. 4 but showing the parts of the pad separated as. they appear prior to association.

A pad of the character disclosed may be turned or otherwise formed from wood, and blown or molded in several ways .from vul canized rubber, but it is desirable under many conditions to produce a pad which may be economically manufactured from paper ber or hard rubber substitutes, from which the pad ,can notaforesaid ways.

My invention provides a construction and a method of manufacture whereby pads of the character specified may be-made from liber or any of the ordinary hard rubber f substitutes in a' satisfactory, reliable and comparatively inexpensive manner. n

The pad 1 maybe of any suitable form for the purposes and comprises a body member 2 and a closure member 3.. The body member 2 is herein shown as of substantially economical formation, comprising a crown portion 4 and a base portion 5, the crestlor Aapex of the portion 4 constituting the bearl lng face of the pad, which is providedA with be formed in 'the I gradually feeds through' the outlet 5 and is an -outlet 5 for thel discharge of the medicament.

rI he portion 2 is hollow and forms a chamber -6 in whichl the medicament is stored, and in practice the sealed or closed base portion of the pad is fastened or applied in any suitable manner to a supporting device of any preferred construction, whereby the pad is secured upon thefperson of the wearer. As shown, the base 5 has an opening 7 of materially greater diameter' than the opening 5 and which receives the closure member 3. This opening 7 may be o'f any suitable shape, but is preferably circular'in outline, as shown, and the closure member 3 is preferably 'in the form of a circular disky which is threaded, cemented or otherwise secured .within the opening 7 so as to lie flush with the outer surface ofthe .base 5, thus closing the chamber 6 and making the base portion 5 solid across the back of the pad to enable it to be properly applied to the'supporter.

The edges of the opening# and disk 3 are preferably rabbeted or chamfered to lap and form a'close joint, whereby a tight connection and sealing action is afforded. The body member 1 and closure member 3, in the process of manufacture of the pad, are separately molded from .the paper ber or hard rubber substitute and then -assembled and united in the manner described. By this means I am enabled to produce a hollow.

body from materials of the character specified which can not be blown or molded otherwise in a satisfactory manner, vthe finished pad being for all purposesas strong and durable as if blown ormolded in a single piece. A pad thus made providesa storage chamber or cavity 6 of some considerable size to receivel the charge of medicament which absorbed -by the tissues, by'which the parts under treatment are strengthened and relief .afforded or such an action induced as to restore normal conditions.v While the form of pad herein shownis preferred, it will of course b'e understood that lthe exterior configuration ofthe pad may be of a-character adapted for the, treat- 'ment of any 4form of hernia.

- I claim I y 1. A truss pad comprising a substantially flat base, plate having a a't'inner face and' a central projection from i'ts outer face, said projection consisting cfa hollow boss of a-P proximately irusto-conical vform, said base plate having a l circular opening therethrough communicating with. the cavity of the boss.. and said boss being provided With an opening in the apex thereof, said boss eX- tending `throughout its area beyond the outer face of the base plateand a lat circular disk peripherally secured Within the circular opening in the base. plate lso as to lie Wholly Within said opening and having a flat outer` face lying flush with the rear' face of said base plate.

2. A truss pad comprising a-substantially' flat basepla-te having a fiat inner face and a central projection from its outer face, said projection consisting of a hollow boss of approximately frusto-conical forni, said base plate having a circular opening therethrough communicating with the cavity of the boss and formed with screw threads therein, the said boss being provided with an. opening in the apex thereof and extending,- throughout its area beyond the outer face of the baseplate, and a dat circulai disk having peripheral threads engaging the threads of plate,vwhereby said disk is secured wholly Within the opening, the disk being provided with a fiat outer face lying flush with the rear face of said base plate.

In' testimony whereof I afii'x my signature inpresence of two Witnesses.
